Green Wood Finishes

Natural oils and waxes are the most eco-friendly of wood finishes, although synthetic alternatives do exist. Beeswax and linseed oil are well known green finishes, but look out for safflower oil and carnauba wax as well. Water-based varnishes and stains also have good green credentials. Look at the manufacturer's label, check for any VOC content and determine exactly what ingredients have been used. For the application of eco-friendly products, follow the guide below.

Wood Finishes

Natural wood finishes, especially those that soak into the grain, are often difficult to remove, so take time to think about your requirements and choose the right product. Protection offered by natural finishes varies. Dye, for example, may offer no protection by itself. Always buy a suitable interior or exterior formula. Consider if you want an almost invisible coat or would prefer some color or gloss. Also, think about how much time you are prepared to spend on application—there may be one-coat options available. Finally, look out for eco-friendly options, such as water-based varnishes and stains or products made from 100-percent natural ingredients.
